Once you understand that those are very strong and use them half dose of what manufacturers are saying, it is a very good product. Cant compare with other nutrients as ive only used those but very happy with the results
Rust spots could be fungus but if you rub the spot with your finger and some doesn't come off innyour finger then it isnt rust spots. Magnesium or calcium shortage as well. Or lockout do to to much nutes or improper ph. Also can happen if you use cal/mg to often. Cheers
Sup Bruva....Definitely.. i want to say you actually a bit over already. You want to harvest your plants when about 60-70% of the trichomes go milky. Get a jewelers loupe if you don't have one.
The more see thru the trichomes.... bud tends to have more of a sativa effect.
The more milky/white the trichomes..bud tends to have more of a indica effect..
Hope that helps a bit.
Happy growing! π¬
